Went there and checked in with Yelp and waited awhile (not too bad actually, stood at the bar and caught the tail end of happy hour -- half price drafts!), was then told there were 14 parties ahead of us on the app, went back to check with the hostess who seated us immediately -- she said she wasn't checking the app? Weird. Anyway, the service was pretty mediocre. I think the food at D's is pretty good but I think the hot dogs are overpriced, I mean $5.60 a hot dog is kind of ridiculous especially when you consider most people are ordering multiple hot dogs and apps/sides. I do recommend the "Angry Tiki" dog, it's the best! It'd be nice if they had some multi-dog deals? Definitely a great beer selection though, the cave is impressive.
