I've been to this place 4 or 5 times now and each time has been the same story:
a) went there because it was local, and was up for Thai food.
b) arrived, and plenty of tables available.
c) waited AGES to get a drinks order in, let alone one for food.
d) food is "ok". I've spent a decent amount of time in Thailand - it's OK, but not stunning.
e) the service delivering your meals is slow, clearing is slow, drinks are slow, etc etc.
f) the bill is *reasonable* for the food, but if basing it on the service, overpriced.
I would love to say this is a one-off / busy occasion during which we visited, but it's not. It's been a consistent pattern for the past 4/5 visits. Good for an ExPat "safe-haven" but you really are being overcharged. Try the local (non-ExPat) Thai restaurants to experience better food, lower prices and superior service.
