Sa Bai's two locations, one (recently renovated) on the near West Side, one further West on Odana's restaurant strip, serve reliably satisfying and tasty Thai food and are justifiably local favorites in a town that loves Thai food and supports quite a few of them for a city of its size. Atmosphere is quite attractive and comfortable in both locations. There is a large menu with many delights; at least until recently, the Odana (not Obama, not Osama) location had several additional dishes, especially good at dinnertime. The chefs are cooperative with spicing requests, allowing for more assertive dishes than are available in most Madison Asian restaurants. Food usually tastes fresh and lively. Soups and noodle dishes are usually excellent. Service at the University Ave location is usually quite good; the Odana location is spottier, often with long waits at dinnertime. We've had good luck with delivery from the Odana location, although certain dishes (e.g., duck) are best when eaten fresh from the kitchen.
