We're travelling in to the area this weekend for a conference in MD and will be based in Bethesda near the main commercial strips. We'll have a car also. Surprised to see not one listing on Chowhound about Bethesda--thought there were quite a few eateries there? Anyway, we're hoping to get some help on the best places to target. Any ethnicity is fine, pref for local places over national chains but more focused on the best food. Can be moderate or higher end. Walking distance from the main commercial area would be great but not at all required. Thank you!!
