I've eaten here a few times and today I went for lunch with my dad. When we arrived, we were seated promptly and our server took our drink orders right away. It was after the lunch rush on a Saturday afternoon so it was quiet.
My dad ordered a Heineken on tap and the server informed us (when dropping off my drink) that the keg was being changed so it would be a few minutes. Having been a bartender, I know how long it takes to change a keg and it took a while longer than usual for him to get his beer; it almost seemed like the server had forgotten it. Thankfully when it arrived, it was clear that it had been freshly poured.
We both ordered off the express lunch menu, my dad got pulled pork and I got a turkey, apple, cranberry, bacon wrap thing. My dad really enjoyed his sandwich and cleaned his plate. My wrap was okay but it didn't really fit together and there was too much mayo. Wraps are normally fool proof but this one fell short for me.
Once we had finished we were chatting (not in a rush) but it took at least 10-15 minutes for our plates to be cleared an the MOD (manager on duty) walked by us a number of times. It was a bit busier by now and I think our server was over-sat and perhaps "in the weeds".
Overall an ok meal, but I have had better there. I wouldnt recommend Montanas for lunch but I would try again. It's definitely a good dinner place though!
