Due to the location and the fact that I've worked within steps of Bridges for the past decade I've dined here many times - for breakfast, lunch and dinner.
The breakfast options are pretty good with a nice assortment of omelets. I believe they have a breakfast buffet occasionally but I haven't had that for several years.
They will give discounts to Pitt employees for lunch, which is nice. Good assortment of burgers and sandwiches and some interesting pizzas. Prices for lunch are a little high.
I like Bridges best for happy hour when the weather is nice. They have an excellent patio outside that can accommodate large and small groups. They have specials on drafts and appetizers.
If you're in town for business and staying at the hotel this is a nice option for a meal. If you're here to visit campus with potential Pitt students I'd suggest going out and about in Oakland to try something else - this is more of a business persons restaurant and not a fun college student spot.
Servers are typically very friendly and hardworking.
