El Gaucho Sukhumvit Soi 19 is a steakhouse near Asok Station in Bangkok that serves US Prime, Australian, and wagyu steaks. Its signature dishes are the T-bone and the wagyu tenderloin set, which can be ordered rare, and the bread before the meal comes with free refills. Same-day Google reservations can seat you at a window table on the second floor, and the entire building is the restaurant, so the space is large. Steak sauce costs extra.
