I made quite a few of those.
Two slices of hamburger cheese, mayo, tomotos and lettuce. Thats it ! (or sauces)
I was a veggie then so used to have that as my on shift lunch , with chips and chilli sauce.
people forget that until the late 80s/early 90s the number of McDonalds/Burger Kings etc in the UK were very limited. Grubbs and Uncle Sams in the mid to late 80s were your burger choices In Brighton. I used to go Wimpys in the 70s in East Street as a teenager for a treat. There wasn't anywhere...
I worked in Uncle Sam's in 1988/89. Amazed it seems to be thriving.
I always thought its home made chilli sauce was , and still is, the best burger chilli sauce i've ever had. Wonder if they still use the same recipe. Is it still up to scratch @Tom Hark Preston Park ?
