I've worked in Sylmar for 5 years... here are my top picks :D
You have to try Buffalo Bruce's on Hubbard. Vivian (the owner) makes the best teas/coffees ever and has a different home-cooked lunch special every day.
Excellent sandwiches & salads, great drinks. Plus a super-cute outdoor patio with christmas lights. Try the caesar salad wrap! http://www.yelp.com/biz/house-of-brews-san-fernando
The best $2 tacos ever:
Good thai food: http://www.yelp.com/biz/dome-pochana-sylmar
Good all-around Mexican: http://www.yelp.com/biz/las-lomas-res...
stuck at olive view? the only places i've tried have been taco rico and la carrasca. if you go to taco rico, stick to the tacos. i preferred the hard shelled versions. la carrasca had pretty good goat soup and their burritos weren't bad. all in all, if you're in sylmar stick to mexican.

I worked near sylmar for a couple years... these were the best I found around town:
H. Salt Fish & Chips 1017 Truman St, San Fernando
Sierra's Restaurant (mexican), 500 San Fernando Mission Blvd, San Fernando, CA 91340
Sub Queen, on foothill, not sure of exact address
Burrito Factory, 13867 Foothill Blv. #3
and I second Caruso's... quite tasty.
