Venture down an unassuming side street off the main square and you will stumble across this tiny subterranean cellar café. It's situated at the bottom of what was once a public well, and the exposed brick walls, vaulted ceilings, and candlelit tables make a lovely setting for sipping a coffee or soda. There are also (very cheap) homemade sandwiches and cookies on offer.
