We are staying at Essex House and I'd love a good, casual, moderately priced restaurant near the hotel we can just waltz into without reservations. I've made ressies every night of our trip that will require $$$ and taxis. If it's not possible to get in anywhere decent without reservations, then just a couple recommendations in the area would be fine just the same. Ethnic is fine, but nothing too heavy, and hubby doesn't want sushi although I love it. Is Tavern on the Green really that bad?
