Phoenix Road plus Brill Place connects Eversholt Street with Midland Road and is in principle an excellent pedestrian and cycle link between Euston and Kings Cross/St Pancras stations. But it is not attractive, especially for pedestrians. Camden have money from HS2 to improve it and have come up with a set of ideas which are set out in two large and very thorough reports which are available here and here.
