some of the tastiest sandwiches i've ever had are at jack's restaurant, and if you are a resident of cerritos, they frequently mail out coupons for dinner deals. i would compare this to a more 'homely' Denny's with better service as the waitresses are very attentive to your needs.
I would recommend the club sandwich, meatloaf, and their steak/pork chop dinners are always a safe bet.
plus you can order beer! this place is definitely A-OK! It is not that pricey, as you can expect to pay no more than $10-11 for dinner including tip.
