Several years ago, a couple coworkers took me out to lunch at Lenny's. Over the years, I've been back on several occasions and have consistently had an excellent experience. The only reason I don't go all the time is that I live quite a ways away.
Lenny's burgers remind me of summertime backyard BBQ's. The restaurant is definitely nothing fancy, but that helps contribute to the casual feeling of eating burgers in my backyard. All in all, the place gives off good vibes.
Outside of the burgers, the fries are good (lightly seasoned) and the shakes fit in just right.
So, whenever I need to get my fix for that chargrilled, backyard flavor, this is my go-to place. I always leave good n' full and in a great mood!
