The Sala Thai in Arlington has been advertising a promotion for 2 soft-shell crabs for 10.95 on Mondays. They have multiple signs on the outside of the restaurant, and when you go in it is listed on a board as the special. I was very surprised to learn then, upon going there to lunch today, that no soft-shells would be available, because "the order hadn't come in yet". I was told this after I was already seated etc & had already ordered drinks/appetizer, I think it's ridiculous to have these promotions unless they're going to have the product available (it wasn't like they were sold out, the restaurant was virtually empty). The seafood dish I got instead was "okay", and the house salad was mostly nasty iceburg lettuce....I knew Sala Thai was a middling chain to begin with, but now I have even less reason to return.
