I love this place. At a time when Coventry is overrun by 22-year old douchebags picking fights on the sidewalk after they spill out of McNulty's, The Cave is a welcome, hidden basement sanctuary with a great beer cooler and wine list. Say what you want about the hipster-ish crowd, it's a heck of a lot better than the idiots milling around outside. I love the atmosphere here - it's dark, intimate and great for a date. It has an old-world feel to it that the trendy wine bars popping up everywhere seem to lack.
It starts getting crowded after 9pm, so arrive a little earlier to grab a table and enjoy the evening. Bring quarters for parking (this is Cleveland Heights, after all), and you may get spotty service after it gets busy.
