Need very cheap BYOB for Sunday night
A schoolteacher friend of mine with a very restricted budget is coming for a visit. I'm stumped trying to think of a cheap BYOB with a nice/decent atmosphere. Vientiane would be perfect, except that they are closed on Sundays. I'm looking for a full-serve place where we can get out for $20 each (shared app and an entree each, tax and tip included).
All neighborhoods are welcome, and there are no dietary restrictions. I just thought of Pura Vida -- any others?
