I may be a lone voice here, but I feel the need to defend the existence of Silver Spring's chain restaurants.
The frequently-repeated argument that the chain restaurants on Ellsworth/Hellsworth/The Promenade have somehow done irreparable harm to the family-owned, non-chain businesses is bogus. I have posed the question before, and have to ask it again: where in Silver Spring has a chain restaurant ever directly replaced a "local" restaurant? (Bonus points for naming one that was actually worth eating at.) I can only think of cases where it was the other way around, such as Langano replacing a Jerry's Subs.
If there were no restaurants on Ellsworth before the arrival of DTSS, how could chains have replaced them? You know what restaurant I remember on Ellsworth? McDonald's. A lot of good new restaurants have opened up outside of that two-block stretch since the development was built. Olazzo, Nicaro, Ghar-e-Kebab, Ray's the Classics and Taste of Jerusalem are just a few ones I can name off the top of my head. I think it is fair to assume that some/most of these places would never had opened had the DTSS development not acted as the catalyst that started attracting more people to Silver Spring in the evenings and weekends. In addition to the new restaurants that have opened since 2003, Silver Spring stalwarts like Negril seem to be doing okay, as the Jamaican eatery expanded with a take-out-only storefront in the last year or two. Plus, it should also be mentioned that DTSS has its own non-chain restaurants, such as Ceviche and McGinty's.
If anything, the existence of DTSS's chain restaurants, while grotesque and incomprehensible to many, has in my opinion been generally positive for the restaurant scene in Silver Spring. It reminds me of the conventional wisdom that Starbucks kills off independent coffee houses, while the reality is that the chain helps independents immeasurably, having dramatically grown the market for expensive coffee drinks. Independent coffee places actually want to move in next door to Starbucks.
I also don't subscribe to the idea that people who frequent chain restaurants would be patronizing some "local" restaurant if said chain restaurant didn't exist. I doubt the clientele of the Red Lobster would be necessarily be eating at (insert name of oppressed local restaurant here) had the seafood chain not opened a location on Ellsworth. The only difference would be that those people would be driving farther to get to a different Red Lobster. You wouldn't catch me dead in the Red Lobster, but if that's your bag, enjoy. The sad truth is that these type of restaurants fill a need. There exists a certain segment of the population that WILL NOT try any unknown places, especially ones that are "ethnic", no matter how much you try to convince them. (These are generally co-workers, because let's be honest - you don't really want to be friends with people like that.) So, for business lunches to exist - and for you to get company-paid meals - you need these chain restaurants around.
From a property manager's perspective, it makes a lot more sense to lease space to a known quantity that has a history of success. While the frequently-quoted statistic that 90% of restaurants fail in the first year may be a myth, the figure is still close to 60%. It doesn't do anyone any good to have constant turnover and empty storefronts, especially if the goal was to attract customers to a previously-dead area, such as Ellsworth Drive.
Finally, just because a restaurant is not a chain doesn't mean it's actually any good - and that chains are bad by default. At least chains have minimum quality standards that they are required to meet and are held accountable by the corporate parent. I've had plenty of terrible experiences in some of Silver Spring's precious local restaurants, many of which I no longer frequent. I personally don't frequently eat at the chain restaurants in Silver Spring, but I don't mind occasionally getting takeout from places like Chipotle or Baja Fresh when it's convenient.
If you don't like the chain restaurants, don't eat at them. Just think of them a necessary evil. I don't know where in the western world these days you will find a urban area that doesn't have its share of chain restaurants. New York, London, take your pick. I don't know why Silver Spring always seems to bear the brunt of chain hatred in the DC metro area, because other places surely have their share. Check out Dupont Circle (just one example), where you will find Potbelly, Chipotle, Five Guys, Cosi, and Subway on a single block.
