Private Rooms for a Party of About 20
A group of around 20 has the most choices. Walter’s can section off its patio with a bench and a private bar for 20, which works for a relaxed party where people want to stand, talk, and eat barbecue.

What a Private Party Room Costs
Most of these restaurants don’t print a room price on their private dining pages, so the cost comes from a conversation with the event team. Monterey Bay Fish Grotto is the exception here, with a layout, features, and pricing sheet linked under each room.
When you ask for a quote, you will receive an answer on each of these:
- Is there a food and drink minimum for the room, and does it change by day or time?
- Is there a separate room fee, or does the minimum cover the room?
- Does the bill add tax, gratuity, or a service charge on top?
- Do you order from the regular menu or a set event menu?
- How is the bar billed?

When the Party Is Too Big for a Restaurant Room
If you want a room you can set up your way or more space than a restaurant room offers, a dedicated private event space in Pittsburgh is the other option. Published sizes run from 50 seated at Engine House 25 to about 350 seated at the Grand Hall. These venues rent you the space, and you may need to bring in a caterer.
- Engine House 25, a restored firehouse at 3339 Penn Avenue, lists a maximum of 50 guests seated or 100 for a standing reception.
- The Art Room at 2010 Smallman Street seats up to 150 and holds up to 200 for standing.
- Pittsburgh’s Grand Hall at the Priory, in the former St. Mary’s Church at 614 Pressley Street, seats about 350 with a dance floor, and its courtyard takes cocktail events of up to 150.
If you book one of these and want barbecue on the menu, Walter’s team will cater at an event space you’ve already rented. BBQ catering orders in Pittsburgh need one week’s notice, and you can pick them up or have them delivered.

Private Parties at Walter’s BBQ Southern Kitchen
Walter’s hosts birthdays, corporate events, family reunions, and other special occasions at 4501 Butler St in Pittsburgh. The space is outdoors and relaxed, which suits a group that would rather mingle over Walter’s 14-hour brisket and other smoked meats than sit through a formal dinner.
- The tent seats up to 65 guests.
- The team can section off the patio with a bench and a private bar for 20 more.
- Together, that’s 85 guests seated at one time, and the team can add tables just outside the tent.
For a cold-weather date, Walter’s on-site smoker adds warmth to the outdoor seating in the cooler months. The team shares how it handles winter service in keeping an outdoor BBQ buffet hot in Pittsburgh’s cold weather.
For help with portions, read the guide to planning a BBQ catering menu for a large outdoor event. To see what Walter’s serves, browse the dinner and brunch menus.
Smaller groups that don’t need a private space can call ahead, since Walter’s takes limited reservations for parties of 10 or more.
Have your date, guest count, and whether you want the tent, the patio, or both ready, then check availability with the team.
