It certainly has a local feel. And I imagine that if you are from provincial Bristol and have been dining there since you were a kid then it has nostalgia. But the atmosphere is non-existent (plastic tables and chairs overlooking a dirt parking lot), the service is mediocre (Tweets' family members and friends who are not motivated to provide that extra care), and the food is good, but not great. The menu hasn't changed in years and the signature dish, a red or white seafood pasta, is good but it lacks flare - there's nothing ""special"" about it. If you're just looking for a plate of pasta, Tweet's is fine. But if you're looking to enjoy a night out, perhaps a family dinner or a date at an interesting restaurant, then keep driving.
Pros: It's cheap
Cons: It feels cheap.
