Bier Markt is a solid choice for a happy hour and it's usually not too busy so getting a table for a group without a reservation has been doable on the occasions that I've gone. Happy hour menu is a good deal. There is usually a decent selection of drafts and the food is okay for the price. Overall you get what you pay for so the burger, pizza, etc. isn't anything to rave about, but it's not bad. I tried the pizza on the happy hour menu, which I would probably skip next time around. Its hard to complain too much since it was only $5. I found it especially greasy and the crust was nothing special. I do like their fries though.
Service has also been overall good. They are able to accommodate larger parties and don't seem to have any trouble splitting the checks at the end. Waiters are fairly attentive and they are prompt about getting drinks to the table.
