Welcome to Carlsbad! My hubby and I are also having date night same night! If you do go to Coyote grill, heads up that the music is outside and they allow smoking outdoors. They do have a few fire pits, and depending on when you're there, the trains might come by-- but the food is good!. In that same complex is a Mediterranean rest. and they have live music and fun seating/atmosphere--if you end up there, check it out--there was great music when we were there. Not sure if you are into wine bars, but Relm is pretty new (on State St.) and they have a great atmosphere, good wines, and good food/appetizers, decent prices, and good service (also an informal art gallery). Paon (corner of Cbad Vill Dr and Roosevelt) has a cool wine tasting room and decent food in the restaurant (if you like French food). Bistro West is another good place for a lounge (drinks, apps, desserts). On the other end of the spectrum is Dini's which is right across the street from the beach and draws the younger crowd, but can be a fun pit stop, though, especially for late night night life! Hennesseys and Hensleys are other options for casual atmospheres with music. If you're looking for a true "club" atmosphere, you'll have to leave Cbad! Belly Up (Solana Beach) is a great place, but you'll need to check if you need tixs for the night you are going. You might be able to take the Coaster down (prob need a cab back if it's too late).Le Papagayo (in Leucadia) is fun and trendy, but usually books up in advance. Other ideas (more fun than romantic) are K-1 Speed in Cbad (adult go-kart racing), driving range at the Carlsbad Golf center and bowling at Surf Bowl (Oceanside).
Hope you have a great Valentine's Celebration! Let me know if you come up with other ideas...we're always looking for new fun ideas "close" to us! Have fun!
