Weighty, messy, exotic burgers draw a diverse patronage to this cramped Kirkman Road joint. Hot dogs, beef skewers, arepas and other South American fare are offered, but it's the burgers -- hand-formed patties piled high with lettuce, tomato, white cheese, onion, and a mix of potato chips, pineapple sauce, pink sauce and Garcia's delectable secret garlic sauce -- that rule. Open until 3:30 a.m. Sunday through Thursday and 4:30 a.m. Friday and Saturday.
