I'm in Manchester. If you look on the gov.uk site you can find the details. So long as you're not meeting in a private house or garden, I think you're not breaking the law, just going against guidance which advises not to meet people from other households in a public venue (I would assume this means hotels too). The rule of six is still law too, but assume you'll be less than six anyway.
For the Manchester local restrictions the law says:
If you live in one of the affected areas, in order to help prevent the spread of coronavirus you must not:
host people you do not live with in your home or garden, unless they’re in your support or childcare bubble
meet people you do not live with in their home or garden, whether inside or outside the affected local areas, unless they’re in your support or childcare bubble
The Manchester local restrictions guidance (not law) says:
In the affected local areas, we also advise that you should not:
meet with people you do not live with, unless they’re in your support bubble, in any public venue. Examples of public venues include pubs, bars, restaurants and cafes places of worship, community centres, leisure and entertainment venues, or visitor attractions and parks. This also includes outdoor areas of these venues (such as a beer garden) and areas directly outside them, such as the pavement or road. Further examples include shops, places of worship, community centres, leisure and entertainment venues, or visitor attractions and parks. This applies to visiting venues inside and outside of the affected areas
visit friends or family in care homes, other than in exceptional circumstances. Care homes should restrict visits to these circumstances
