This place is a good option for those who want to try some Spanish mini-sandwiches and beer in a casual setting. The chain offers a variety of mini-sandwiches and a good selection of beers and wines. The prices are reasonable and the atmosphere is cozy, making it a good spot for a quick bite or a casual dinner. However, it can get quite busy and loud, especially during peak hours. Some customers have mentioned that the service can be a bit slow or unfriendly, but overall the experience is pleasant. The location is convenient, with a paid parking lot nearby. One of the issues is that the staff can be a bit rude or dismissive, but it seems to be an isolated incident rather than a widespread problem. Overall, 100 Montaditos is a solid choice for those looking for a quick and affordable meal in a casual setting.
