So my dad owns his own small diner, and he wants to set up wifi there. I'll talk to him today to see if he knows the over all size in, but the total seating capacity is about 75 at tables with 25 more bar stools in 2 rooms. The building is a bit older, so my guess the wall are more concrete/brink that what ever they would be now, so a stronger signal would be helpful to go with higher connections allowed. Budget wise, I'd say is probably about $100-120.. Thanks!
