My family, immediate relatives and friends are making arrangements to visit this restaurant to celebrate someone's birthday. Is there a parking lot and is it free? Also, is the building big enough to accommodate 10-20 people in one visit?

They have a decent sized parking lot and it is free to park. The room upstairs can accommodate large groups. I would call before you show so they can accommodate your needs.

Parking is free, and yes to the party size

Yes it has a big parking lot and a room for parties.

Yes there is free parking and 10-20 people is not a problem. We are usually a party of 10 when we go.
