Recently I was so happy to be able to revisit a two-block stretch of Grand Street. It's one of my favorite places for good snacks - let's call this Lower East Side strip the Walk of Nosh.

Doughnut Plant

First up: Doughnut Plant at 379 Grand. At this eight-year-old landmark, the doughnuts, made fresh daily, are much more intensely (and often unusually) flavored than the much more boring options elsewhere. Think grapefruit, peanut butter and jelly, even marzipan, and not just vanilla or chocolate. Lavender and blueberry were options the day I went, but I went for the tres leches, a takeoff on the Latin cake of the same name. Covered in a crisp, pale-white frosting, this doughnut had been soaked in sweet milk, making for a gooey interior. A tip: if you do head here, don't go too late in the day: when the day's allotment are gone, they're really gone.

Kossar's Bialys

A couple doors down from Doughnut Plant, at 367 Grand, is a much older and traditional carb-seller: Kossar’s Bialys. Although you can get bagels at this bakery, the real reason for coming is the bialy, a flatter, denser bagel variant that comes with a mass of smashed onions in the center. It addition to being delicious, those bialys are also a reminder of the area's heritage. At one time, Grand Street, like most of the L.E.S., was intensely Jewish. The neighborhood has changed in many ways since then, but Kossar's and many other kosher and Jewish places remain in and around Grand Street.

Pickle Guys

With your dougnut and bialy needs taken care of, there are lots of other places nearby worth checking out. If you're seeking something salty and sour, head to nearby Essex Street for the Pickle Guys, where its pickled vegetables of all sorts are stored in large open tubs. Sure, the pickles are great, but I also love the giardinera, a heavily brined mix of carrots, cauliflower, red pepper, and celery that's very good at a picnic.

Isabella's Oven

If pizza's on your mind, Isabella’s Oven, at 365 Grand, makes a tasty, albeit somewhat pricey, option -- bonus points for the charming small garden in back. Farther east, at 409 Grand, is the laidback Roots and Vine cafe, serving wine and beer as well as coffee. Either place is a good spot for plotting and planning your next NYC destination.

A few days ago I took the subway up to Harlem as part of research for a New York City travel guide I'm working on. Although 125th Street is the first Harlem stop for most tourists, much of it is too crowded, with lots of shopping but not always enough excitement. The same couldn't be said of my ultimate destination: 116th Street near St. Nicholas Avenue. The area's sometimes called Le Petit Senegal because of the large number of immigrants it attracts from that West African country.

It's important for travelers, even those in their own city, to have priorities. Mine happened to be lunch, so I walked straight ftoor Amy Ruth's, one of the best-known soul food restaurants in Harlem. Here the dishes are named for notable African Americans. I got the "Reverend Al Sharpton" -- the classic combination of chicken and waffles.

You can get the chicken either fried (my favorite) or "smothered" (covered in gravy). The chicken, prepared immediately before it arrived on my plate, was juicy and tender, and I ate it in the traditional way, with lots of maple syrup covering the chicken and soaking into the ridges of the waffles. Delicious.

I also got "sweet tea"-- ice tea with as much sugar as can possibly be dissolved in it. You know what to expect when something's called "sweet tea," but Amy Ruth's version took the concept to new levels of syrupiness. I actually considered watering it down to make it just excessively sweet.

Looking out Amy Ruth's picture window, I checked the progress of one of the many condominiums going up in Harlem. This 16-story example was built in partnership with its next-door neighbor, the Malcolm Shabazz Mosque -- the new building actually cantilevers out over its roof.

The mosque, originally a casino, is hardly the most beautiful thing in town -- a major architectural guide calls it "vulgar" -- but what it lacks in sleekness it may make up for in historical interest. When it first became a house of worship in the 1960s, it was part of the Nation of Islam, and Malcolm X preached there. Later, after he was assassinated, the mosque was renamed for the name Malcolm took soon before his death, and its ties with the Nation of Islam were cut. The congregation these days includes many Senegalese.

Now, fortified by fried food and a whole lot of sugar, it was time to hit the road again. I walked a few blocks west to one of my favorite bakeries, Make My Cake. For me the only choice here is the Red Velvet Cake, an otherwise fairly straightforward classic that gets its lurid hue from huge amounts of food coloring and much of its flavor from the tangy cream-cheese frosting. Sadly I was too full of chicken and sweet tea to get anything then. Like me, you'll have to be satisfied with just a picture until you can find your own way up to 116th Street.

There are several Chinatowns throughout New York City, but for most tourists, the one in Manhattan is the best to head to. This is the one with all the knockoff handbags and other glittery objects for sale -- an attraction that leaves me cold. Instead, I'd say to head here for the food shops and markets, the restaurants, and the sheer excitement of walking along some very frantic, very old streets.

Chinatown is big, but not so big that you can't wander through most of it in an afternoon. But if you're into streamlining, center your walk on Mott Street, which is sort of the neighborhood's "Main Street" -- if you're heading south, the Chinatown portion starts near Mott's intersection with Kenmare Street. Below are a few of the many stops worth making.

Ten Ren, at 75 Mott, carries a large, almost overwhelming, supply of high-end teas as well as teapots and other accessories. The cheapest loose tea here is about $9 a pound ($20 a kilo), and prices increase drastically for anything better. The store also runs a tea shop a few doors north, at 79 Mott -- it's a good bet for bubble tea and people-watching.

There are lots of decent-to-excellent restaurants in and around Mott Street. One standout is the accurately named Amazing 66, which opened a couple years ago at 66 Mott and has quickly gained a loyal following. The Cantonese dishes here tend to be simple, without anything too fussy. I like the congees, savory rice porridges that are very filling and especially comforting on a chilly day.

If your sweet tooth is acting up, make a slight detour at Bayard Street and walk half a block to #65, home of the Chinatown Ice Cream Factory. Here the list of flavors are divided into two groups. Options like the subtle almond cookie, green tea, and red bean are all called "regular flavors," and much more common choices like vanilla fudge, pistachio, and coffee are the "exotics." Whichever category you choose, the ice cream's great (and so is the blog, by the way).

A few blocks farther south is another good stop for sweets. Aji Ichiban, a branch of a Hong Kong chain of confectionary stores, sells candy, dried fruit, and some savory options. Most items are sold by the 1/4 pound, and with such a big variety, it's a good place to putting together a thank you gift or a snack bag for a trip. Samples of most of the fruits are available, but if you're completely flummoxed, go for the hazelnut nougat or anything in an appealing wrapper.
