If you're going for dinner and are mostly interested in small plates, dim sum, and sushi rolls, you're better off paying OOP and applying those two credits/person to upgrading other 1TS meals to Signatures.
Depending on what you order, the value isn't even as good as some 1TS. For instance, someone ordering soup, 2 sushi rolls, dessert and a non-alcoholic drink would be using 2 credits for a $45 dinner (less than a 1TS character meal, for instance).
Most of the entrees (or 2 items that can be combined as an entree) are much cheaper than other 2TS restaurants, with just a few exceptions like the filet.
Unless it has changed, lunch is 1 credit, which makes it much better use of the DxDP.
