Holy cheeseburger, Mueller's! I was unprepared for that deliciousness. In a classic novice move, I ordered a reuben (which was actually delicious- the best corned beef I've seen in this town) and had to endure some serious order envy after a couple of nibbles at my dining companion's burger. Great tomato and cuke salad. Great (free!) banana pudding was slipped to us mid-meal- not sure if that is normal or we were just so charming that they felt we deserved it. But enough about those things- that burger was grilled. It was cooked with just enough pink in the middle. I can't be more specific about it because I was rendered a bit addled with happiness, so just trust that it is delish.
Mueller's is in a weird spot off Providence but I find it to be pleasantly quiet in their little corner. The restaurant is full of random things (let them string your tennis racket and get a free burger!) and some mildly grumpy staff- but I can tell that they are waiting to have their smiles earned by becoming a regular. Which is fine because I plan to become one.
