"Pastry chef here. As much as people say avoid specials, I can't speak for everyone but at least in desserts/breakfast pastries, if you see something new its worth trying. Chances are it's something the chef has been working on for weeks on their own time, there's a lot of love and effort put into it.

Also, the standby if the menu is a book, it's probably not great.

The biggest thing to keep an eye on though imo is the staff. If there's pissed off people, get out as fast as you can obviously. If everyone is kinda apathetic and not talking to each other much, get out. That's also a s@#tty environment, everyone is probably really passive aggressive, and that's going to show. If people seem genuinely good with being there even if it's busy or if there's playful ragging going on, that's where you want to be. The better the staff gets along, the better everthing in the place runs."
