When I stopped to see if there was a web site or opening times on The Pass food truck, a vehicle drew up, to advise me that there are no better burgers in Chichester.
I suspect he was hoping I was there to open up. But no luck so far, I suspect that they only open for lunch.
Usually open between 8am-3pm. Check out their Trip Advisor reviews. Have just opened a burger cafe in Chichester (26 Southgate, off South Street) https://www.tripadvisor.co.uk/Restaurant_Review-g186406-d10678693-Reviews-The_Pass_Street_Food_Cafe-Chichester_West_Sussex_England.html
The most fantastic food outside town as well as in town. I go there whenever I can. No frills, no gimmicks, just proper homemade delicious street food.
I have found their shop around the corner and down the lane. Treat myself to their Mexican Burger at the end of the week. Have also taken a liking to to the Hash Brunch Specials at Charlie Harpers http://chichesterlocal.info/breakfast-in-chichester. Any others you can recommend?
