Newark, Grantham, Stamford?

All, to be fair, clic English small towns, with not a great deal to attract you if you are looking for any degree of excitement. They are similar sizes, similar in ethnic make up (i.e. not terribly cosmopolitan) and while the countryside around them is quite pleasant, the towns themselves are OK but nothing hugely interesting. Grantham has frequently been described as 'the most boring town in England; and having spent a few days there on business I see no reason to disagree. Newark is a centre of the UK antiques trade, meaning that every other shop in town is an antiques place and there is a huge influx of antique dealers several times a year for the big fairs at the showground. Stamford of them all is probably the quaintest town, a few nice enough restaurants, closest to the nicer countryside around Rutland Water and has a brewery which makes amazing apricot beer.
