Jaleo
José Andrés' excursion to Bethesda brings the same excellent modern takes on Spanish tapas and the same excellent sherry and port lists. While extremely popular, this location is big enough where you can get a table without reservations.
Bangkok Garden
This Thai restaurant is one of the best in the D.C. area. It has relatively inexpensive food served in a warm, inviting atmosphere.
Raku
Arguably the best Asian food in Bethesda. It's kid-friendly and rather noisy, but the food is made with incredibly fresh, high quality ingredients, and will not likely disappoint. Very popular so make a reservation or get there early.
Tastee Diner
Looking for the true American diner experience with greasy spoons and waitresses with too much eye shadow? How about cheap eats any time of day or night? Look no further than the tried-and-true Tastee Diner to serve your needs. Indeed, this might be the most dineresque diner in the D.C. area.
Bethesda Crab House
What better reason to cross the District line into Maryland than a Maryland crab feast! This is not a nice restaurant, it is a crab shack that somehow made its way into Bethesda, with the brown paper on the table, buckets of crabs, tons of Old Bay seasoning, and a lot of messy patrons.
South Street Steaks
Philly cheesesteaks. No, really: authentic Philly cheesesteaks on Amoroso rolls, right here at a sit-down eatery in Bethesda, and they taste like you got them right out of Geno's window in Philadelphia. If you're not from Philadelphia, you can look like you are in the know by ordering a "nine or twelve inch whiz wit." Don't worry, they'll understand that, you won't look silly, and you'll get your cheesesteak with the traditional cheese whiz and grilled onions. In addition to legit Philly cheesesteaks and late hours, this eatery draws customers with a bunch of specialty subs, like the missteak, a monstruous sub stuffed with 1 lb steak, 8 pieces bacon, pepperoni, fries, and three types of cheese feeds up to four.
Passage to India
The often fiery cuisine here is some of the best Indian food you'll find anywhere in the metro area, and it's also attractive, rather quiet, and has reliably excellent service. If you are up for a challenge, try to finish one of their vindaloos without asking them to dull down the spice level.
Vace's Italian Deli
The Bethesda Vace's, like the one in the city, serves the best, most authentic New York style pizza you'll find anywhere this far south. Takeout only.
