08/27/2025 - Katelyn R.
Stopped by for a quick breakfast on a busy Saturday morning and was impressed by the variety of bagels, especially the lox with pesto-even if the salmon portion was a bit light. The orange juice tasted fresh and the cozy heater kept me warm despite the chilly weather outside, while the friendly staff hustled to keep up with the morning rush. Though the place has its quirks like a broken front door and occasional wait times, the customizable sandwiches and solid coffee keep me coming back whenever I'm craving a tasty and convenient bite.
