I really liked Simple Bistro in 2012 when I first moved to this neighborhood and still had high hopes for it last year when I wrote my initial review based off of several good meals! I'm not sure what changed, but the last time I ate there - shortly after posting my much more positive review - my meal just wasn't very good compared to previous times I had ordered the same dish (not a hard one: steak frites).
My partner and I decided to wait for them to change to their summer menu so we could try new things (and because in 2012 the prix fixe went down to $35 for summer) and I think they went at least six months without changing anything on the menu... the price definitely didn't go down.
I took a look at their menu while walking by today and found that they've raised their three-course prix fixe from $40 to $45. It's not that big of a difference, but we probably won't bother going back. The discount prix fixe was a lot of what brought us in and I'm not really willing to pay any more without being sure there's been an increase in the quality of the food since our last meal there was sub par.
