Where to grab a handful of the good stuff.

Tribeca Restobar

Run by siblings Rishi and Shareen Arora, Tribeca is one of the few bona fide brunch spots in town. Much of the menu is devoted to hearty egg, pasta and meat dishes, but their sandwich offerings are just as rewarding. Look no further than their classic Reuben (B240), which is an irresistible mix of pastrami, Emmental, sauerkraut and Russian dressing, served on sourdough.

Rocket Coffeebar

Another of the chill café-cum-brunch spots that seem to be popping up all over town, Rocket charms with its low-key location down a quiet but interesting soi, its preponderance of wood and simple menu of interesting dishes and decent coffee. The sandwiches are among the real highlights here spanning simple but tasty combinations like salami-cheese on homemade focaccia (B175), not too cheesy but not too dry, and mild gravlax on Danish rye (B175), topped with refreshing greens and herbs.

BKK Bagel

A lot of people give nods to the proper bagels on offer at BKK Bagel. But it’s also what they put in them that keeps us coming back. Take the shining example of The Verrazano (B225) which embodies many virtues of a good sandwich: minimum fanfare, homemade bread, in-house meat and crunchy freshness. Along with their bagels, they do their own roast beef and dress it with little more than some whole-grain mustard and sauerkraut—delicious.
G/F, Maneeya Center, Phloenchit Rd., 02-254-8157. BTS Phloen Chit. Open Mon-Fri 8:30am-6:30pm; Sat 8:30am-5:30pm

Café Tartine

Café Tartine understand the mass appeal of a simple sandwich containing just a few, top quality ingredients. Still, we feel oh so French munching down on a sandwich like their pate cornichons (B190) with its country-style pork pate complemented by pickled gherkins and onion jam that cuts through the richness of the meat spread, and a slathering of Dijon mustard, all in a crusty baguette. Perfection.

Vietnamese & More

While there are quite a number of Vietnamese restaurants in town, few really nail banh mi, that country’s signature sandwich. That’s where Vietnamese & More steps in. Nestled down a tiny sub-soi, the place offers a bare yet homey décor and a brief yet delicious menu of Vietnamese faves (and, yes, a few Thai and French-influenced dishes). Our favorite sandwich here is the banh mi with succulent beef brisket and blue cheese (B200) and the secret weapon, a side of au jus for dipping.

The Corner

This no-frills new venue does the little things right with a brief menu featuring mostly Mediterranean fare. Chef Cedric Cador makes everything from scratch, including the wonderful baguettes and pita bread used in their sandwiches. The standouts on this front are the Le Provencal (B140), packed with roasted vegetables, olives, parmesan cheese and pesto, and the panini (parma ham, tomato, basil and mozzarella, B160), both served on homemade ciabatta. Simple but very satisfying.
