I hadn't seen this posted here, so I thought I'd mention that Mirna's in Jenkintown started running a Summer prix fixe on July 28th that includes choice of soup, salad, and choice of entree for $20. We ate there last night for the first time in a while and I wish I had known of the special sooner! The soups and salads are in slightly smaller portions than ordering a la carte, but it's not a bad thing as their soups and salads are generally enormous. The entree portions were quite generous and we left feeling pleasantly full.
They didn't say how much longer the special was running, just that it's currently valid Sun - Thurs.
