This Subway 'restaurant' deserves all the bad reviews that they have here on Yelp. I'm surprised to see they're still in business after such bad publicity. This, Subway could probably win the WORST SUBWAY award, in the category of bad Subways on the planet.
I've been here a total of 4 times and 3 experiences out of 4, were a total train wreck. Never have I experienced anything like that, anywhere else combined, let alone, at the same restaurant. At this Subway, everything that can go wrong, will !
First time, the cash register stopped working. Staff tried calling multiple people. I was wondering where the owner was !!?? The owner of this Subway, genuinely raises the bar for the term 'absentee owne.
The line and wait got so long that people (and us) were finally told after 30 long minutes, that they could not be served. We all just left hungry.
Ok, not their fault if the registers don't work. However, similar issue at another Subway in Diamond Bar, and they were able to make things work.
Second time, they ran out of veggie patty. Subway meat sucks. The one thing that they have going for them, they don't have anymore. Great !
Third was not so bad. Used a coupon, got what I ordered, couldn't complain !
Fourth time, today, was surreal ! Lady couldn't understand what I was speaking, refused everything I asked, didn't want to answer any questions, refused to give extra meat even though I offered to pay for it and annoyingly kept saying NO to every little thing. I had to tell her 3 times to scoop out the bread and even then she only scooped out, one side out of 2. Portions were skimpy as always and the bread was barely heated (reading other similar reviews of cold sandwiches, I believe their toaster is broken but they don't want to admit or fix it).
Ultimately, what we got was a cold sandwich bread, with the cold vegetables smudged between a refrigerated veggie patty, along with stringy and rubbery cheese that wasn't melted, but was rather sticking to the patty because of being compressed by the weight of the vegetables and the bread, served by unbelievably rude staff.
Subway, if you are reading this, please have some dignity and close this 'restaurant' after getting such poor reviews. The only thing they have going for them is that they are next to In-N-Out and Chipotle
