Los Cucos at Bee Cave (or Bee Caves...nobody seems to know the whole name story there).
Ate there 2 weeks ago. It was great. Huge portions, too. I actually had to leave some on the plate, which I never do.
The best burger I've had in Austin was at the bowling alley at Burnet and 183. I've got a friend who is a self-proclaimed "burger aficionado", so I've been to most of the trendy places with him. Maybe I just was there on a good day. I haven't been back, as I'm afraid it won't live up the the memory.
eggs, queso, steak, spanish rice, tortilla strips, and whatever salsa you choose. I like the salsa Olivia and the salsa Mexicana personally. I think it comes on a whole wheat tortilla but I dont remember exactly.
Its named after some cop named Kevin who special ordered it all the time and people in line would hear him order it and ask for it too...
