I'm new to the forum but I've been going to the Bear quite regularly this year. It is undoubtably the best pub in Stratford. There's several reasons for this:
The ale is utterly superb. As a CAMRA member I can tell you that the condition of the beer is always very good or excellent. Graham takes great care of the beer and it shows. The 7th handpull is a very welcome addition as is the addition of a dark beer (my whinging finally paid off!

). The staff know about real ale and can usually recommend something if I'm in a non-committal mood. The range is beer is very good and the focus on local beers very commendable.
The staff are friendly and all know what good customer service is about.
Food is uniformly excellent (try the ploughmans - best ever) and the service is never slow.
The decor is comfortable and relaxed and the place is always spotless - a rarity in a good real ale pub.
Watching the rugby in there (especially Wales beating England :clapping

when it's packed is great as you can still get table service. How many pubs in town do that?
It's one of the cheaper places to drink in town - I can only think of the Golden Bee and Lamplighters that are regularly cheaper. If you think £2.90 for a beer that is 5.5% is too expensive then I suggest you'd be better off in Wetherspoons.
Games and newspapers available all the time.
The clientele is varied but always quite relaxed. Never noticed a bad vibe in there once.
It's very difficult to find fault with the place to be honest. A must if you live in or are visiting Stratford.
