On its Facebook wall, Syringa Japanese Restaurant & Sushi Bar, on 4th Street, tells of a disagreement with a customer over a Happy Meal. Seems the customer brought a Happy Meal from McDonalds, for someone in the party (maybe a child) and was told in no uncertain terms that the restaurant didn't allow outside food or drink. The customer then left a note on a napkin saying that Syringa was a favorite eatery but s/he wouldn't be returning. That prompted this response from ownership: "This note was left after I told a table that we don't allow outside food or drink....they brought in a Happy Meal. Yes I made a snide remark about having to throw away a little piece of garbage. Do you think it would be ok to bring Togo food from Syringa into McDonald's? We do not want to see Starbucks, Big Macs, whoppers or iced lattes in our restaurant, we would however love to see people with open minds and smiling faces." (Logo from Syringa Facebook page)
