Most of them went out for the reason of price and quality, and they probably won't come back unless someone starts a new restaurant and just buy a name to get instant recognition. I don't mind them not coming back.
The only one I wish to have, was closed due to pandemic. Specialty Cafe and Bakery. They have some of the best catering sandwich and cookies you can get and I will always go to a lunch meeting if they are the cater, no matter how bad the meeting is. Technically they are not "closed" (opened 1 location back) and technically they are not a chain (husband and wife owned).

I knew someone who previously worked in the corporate office at Specialty's. However, I also remember what it was like when it was pretty new. What it turned into in the late 90s was way different than it was in the early 90s. Back then a sandwich order was mostly thick, sliced bread and not sandwich rolls. Their prices were ridiculously cheap - I mean really cheap for a guy working a part-time and summer job in my college years. I think a rather large chicken salad sandwich (my favorite) on 7-grain wheat was a little over $3. They also sold full loaves of all their breads.
Before they closed I had a business meeting in Mountain View that was catered by the location that I think reopened. I basically got an $18 credit sent by email and was allowed to order (online) whatever I wanted as long as it was under the limit. I couldn't order over the limit and pay the difference though.
Another place I'm kind of bummed about losing is Gordon Biersch, but that's mainly because of the garlic fries. The founder reopened his original location as Dan Gordon's in Palo Alto, and that's gone too. However, I went there before they finally closed and the garlic fries were exactly what I remember from Gordon Biersch.
