For me it's a tie between Earl of Sandwich & Wolfgang Express. We stumbled upon EoS in '07 when we couldn't get into ANY table service restaurant to save our lives. We walked into EoS & even though there was a substanitial line, it moved pretty fast. We were pleasantly surprised with the food. Very good and affordable, too. Would certianly go back.
We've never been to Wolfgang Express, but I checked out the menu just the other day & it sounds wonderful. Am seriously considering it for our arrival day dinner since we're staying at POR & can take a lesurely boat ride to DTD. Sounds like a fun way to start our vacay.
