I agree, it did seem odd not to have at least one token dish. We did ask the server to check with the kitchen to see what they could do, and the options we got back were the chicken pasta minus the chicken, or a sandwich of roasted asparagus. Maybe my colleague is just a picky eater, but neither of those appealed to him, so he stuck with the salad.
It does look like there's a squash curry dish on the dinner menu, but it wasn't offered as an option at the time. That's assuming the dish is vegetarian to begin with.
I took some coworkers to the Barrymore for lunch and a drink, and everything we had was fantastic: french onion soup, calamari, bibb salad with hearts of palm, lomo de cerdo, salmon, and several drinks off the cocktail list. Even the french fries were prepared perfectly, and the prices were a great value. Service was attentive and friendly.
The only thing preventing us from becoming regulars is that vegetarian options on the lunch menu are scarce, with just one appetizer, one salad and no entrees available. If this isn't a concern for your group, though, you'll find the Barrymore to be a jewel tucked away between the Strip and the convention center.
